Brainlet here. I was reading the Wikipedia article on The Size of the Universe and it said the size is unknown, and possibly infinite.

My question is: how could the size be infinite? Isn’t it generally accepted that the Big Bang contained/created and finite amount of matter which continues to expand outward? I mean, I understanding how the space or the nothingness could be infinite, but the amount of galaxies would have to be finite regardless, right?

when they say that during inflation the universe grew from something smaller than a proton to something about the size of a grapefruit, that always means just the speck that became the Observable Universe.
For all anybody knows the total could have been infinite to begin with.
